LOOK FOR BICYCLES.

$PECIFIQA'IIQN forming part of Letters Patent No. 391,241, dated October 16, 1888.

(No model.)

To all whom, it may concern..-

Be it known that we, TURNEY H. GONG- wlinn and EDWIN K. HANLEY, of Elmira, in the county of Chemun g and State of New York, have invented a new and Improved Lock for Bicycles and Similar Vehicles, of which the following is a full, clear, and exact description.

Our invention relates to an improved lock for bicycles, tricycles, tandem, and all that class of wheels, and has for its object to provide a means whereby the wheels may be quickly and conveniently locked, and wherein the lock will be at all times attached to the bicycle in position for use, in such manner as to constitute an ornament, and wherein only a small key need be carried by the rider.

The invention consists in the construction and combination of the several parts, and in the combination of the lock with a bicycle or vehicle of that class, as will be hereinafter fully set forth, and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a side elevation of a bicycle, illustrating the application of the lock; and Fig. 2 is a plan view of the brake and guidelevers and the attached lock. Fig. 3 is a plan view of the lock with the cap-plate removed and a transverse section through the head, and Fig. 4 is a front elevation of the lock and a partial elevation of the brake lever.

in carrying out the invention the lock is constructed with asuitable casing, A, of greater width at the rear end, a, than at the front end, a, the rear end being made, preferably, more or less rounding and the front end more or less concave.

Centrally and longitudinally within the casing a bolt, B, is held to slide between guideposts I) and the sides of the casing at the front end, in which end an opening, Z), is provided to permit the egress of the bolt. The forward end face, if, of the bolt is concaved to correspond with the concavity of the casing and to conform to the contour of the bicycle-head G.

In one longitudinal edge of the bolt, near the rear end, a substantially J-shaped recess, d, is produced, and near said recess, in front of the same, a key-post, d, is vertically secured in the casing, whereby when the key is inserted over the post one tumbler of the bit will enter the recess (1, and by engagement with the walls manipulate the bolt, as illustrated in dotted lines, Fig. 3.

A pin, D, is vertically secured cent-rally of the casing and to the rear of the bolt, projecting above the same, upon which pin a plate, E, is pivoted at one end, the body and other end of the plate being adapted to rest upon the upper surface of the bolt.

About centrally the plate E, which, for convcnience, we designate a locking-plate, an aperture, 0, is produced, essentially rectangular in form, and from the opposing side walls of the said aperture aligning horizontal studs 6 and c are projected. At the rear end of the locking plate, upon that side removed from the key-post, one end of a spring, E, is secured, the other and freeend of which spring is made to bear against the guide-post 1) upon that side of the lockingplate. The lockingplate is of a sufficient width to normally partially cover the bolt-recess (1.

Near the rear end of the bolt, upon the upper face, a boss, F, is produced, extending upward into the aperture of the locking-plate. Longitudinally in the bolt a slot, F, is made, and smaller aligning slots are also produced in the top and bottom sides of the casing.

In the operation of the look, when the key, which is provided with two tumblers, thelower one being the longest, is inserted over the post, the upper tumbler will move the locking-plate to one side before thelower tumbler acts, bringing the boss on the bolt in alignment with the space between the studs, and, as the lower tumbler carries the bolt forward, when the boss passes the studs the upper tumbler disengages from the locking-plate, and the said plate, resuming its normal position, brings the forward side of the stud e in substantial contact with the boss on the bolt,whereby the bolt is locked in an extended position, as illustrated in Fig. 3.

In applying the lock to a bicycle or similar machine a wedge shaped gib, H, is passed through the slot in the casing and bolt to an engagement with their forward walls, and the lock, key-hole upward, is entered by means of the aforesaid slot, over the perpendicular arm h of the brake-lever 1-1, the gib, coming in contact with the face of said arm, opposing the head 0, bringing the front end of the bolt directly opposite the head, as shown in Fig. 1. When the lock and gib have been sufficiently wedged upon the lever, the gib is secured to the lever by aset-screw, h, as shown in Fig. 4:.

When the rider dismounts, he applies the brake on the rubber tire and turns the key in the lock, the bolt of which is thereby forced against the head of the machine, keeping the brake in contact with the tire. Thus it is rendered impossible to ride the machine without throwing back the bolt.

The lock is no trouble to the rider, as it is always in place, the weight upon the machine practically amounts to nothing, and the attachment may be made an ornament b nickelplating or finishing it to correspond with the part to which it is secured.

The key-hole K is made double, in order to foil any one attempting to fit a key to the same.

Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is-

1. In a bicycle or similar machine, the comb'nation, with the brake-lever and head, of a bolt-lock secured to the former, the bolt whereof directly engages the head, substantially in the manner and for the purpose specified.

2. The combination, with the brake-lever of a bicycle or similar vehicle, of -alock having its casing provided with aligning slots to re- 0 ceiveone arm of said lever, substantially as described.

3. In a bicycle or similar machine, the combination, with the brake-lever and the head, of

a iockheld horizontally upon the lever pro- 5 vided with a sliding boltadapted to engage the head, a gib interposed between one edge of the lever and the opposing edge of the lock, and means, substantially as described, for actuating the bolt.

4. In a bicycle or similar machine, the combination, with the brake-lever and head, of a lock provided with a slotted casing, a slotted sliding bolt having a concaved front end and boss upon the upper surface and an essentially 5 V-shaped recess in its longitudinal head, a spring-atuated locking-plate bearing upon said bolt and provided with a central aperture, to receive said boss, and stop arranged in said aperture, a key-post opposite the recess in the 50 bolt, and means, substantially as described, for securing the lock to the brake-lever.
